DENVER -- A group of 21 news organizations is asking a judge to reverse his order sealing court records in the case against James Holmes, the man accused of killing 12 people and injuring 58 in a Colorado movie theater.

The motion was filed Friday in Arapahoe County District Court.

Judge William Blair Sylvester issued an order July 20, the day of the shooting, to keep the documents secret without stating the reason. The news organizations say the order means even a complete list of court filings is kept secret.

The news organizations include The Associated Press, The Denver Post, three other newspapers, four Denver television stations, six broadcast networks and two newspaper groups.

A spokeswoman for the district attorney's office declined to comment. Holmes' attorneys didn't immediately return a call.
